loose controller function after loading game

Hello,
I softmodded my new wii ( 4.3U out of the box, no way to run from dvd drive), I have HBC and bootmii.

I can play some games from a WBFS USB drive, but others I can't. For instance, call of duty heroes 2 loads and when it gets to the very first screen, the warning screen for the movement controller etc.. the wii controller disconnects and does not reconnect, I am forced to restart the wii. This happens with the backup disc channel and the usb cfg loader.
Then another game (tiger woods 2k10) nothing happens, it just freezes, on the backup disc channel I see something about a panic.
